**System Information**
xubuntu 15.10 64bit; nVidia Geforce GTX 780 Ti
**Blender Version**
Broken: Blender 2.67b (for example)
Worked: Blender 2.65a (last working version)
**Short description of error**
impossible to keyframe the layer buttons for objects on panel "Relations"
**Exact steps for others to reproduce the error**
- select a object
- switch in the Properties to tho object options
- hoover the mouse over the layer buttons
- press I to set a Keyframe
- blender will report: ""layers" property cannot be animated"
In my opinion the ability to animate the presence of an object on a layer, is important. Its the simplest way to animate an character grab something, to switch between intact and broken items on impact and so on.
Thank you for investigation!
